Segfault upon any JS exception

[RichardWarfield]

First of all thank you for this amazing project which has been so useful to us.

Describe the bug
Any exception in the JavaScript code now seems to result in a segfault in the Haskell application when using eval. This did not occur with older versions of inline-js; git bisect reports that the first bad commit is ef67574 .

To Reproduce
Please see reproducer here (uses Nix flakes)

Expected behavior
eval throws an exception instead of causing a segfault.

Environment

• OS name + version: Arch Linux, building under Nix
• Version of the code: master branch commit 0fc7444

Thanks for this issue, @RichardWarfield! I was about to give up.

Commit 26c89ec30039445d6b3735cb58fda91b38400375 (i.e. the first commit before ef67574) worked like a charm for my project

Even I am getting this issues. Is there a fix other than moving back few commits?

Code to reprduce this.
